How can I solve this

Tell us what’s happening:

Your code so far

// Initialize these three variables
var a = 5;
var b =10;
var c=6;
c + "I am a String!"

// Do not change code below this line

a = a + 1;
b = b + 5;
c = c + " String!";

Link to the challenge:

var a;
var b;
var c;

1st we check what we learn which is the var a now we need defy them so they are no longer undefied. We do that just like with math with the = sign and the outcome is the one that we are given so: Y A= 5;
Remeber that a variable is like the missing number in a math calculation.

var a= 5;
var b= 10;
var c= "I am a String!";
